Dioptra
Free trial · $450/moAI contract redlining inside Microsoft Word for legal teams
What is Dioptra?
Dioptra generates redlines in Word from your own playbooks, executed contracts or prompts, and flags non-market risk. It is for in-house legal teams and law firms that review a lot of contracts and want edits that stay close to existing language.
Playbook distillation builds a custom AI-ready playbook from executed agreements and standard forms. The tool also searches and extracts terms across contracts, produces issues lists and risk summaries, and includes a secure AI chat assistant.
It handles your own paper and counterparty paper, integrates with workflows such as CRMs and procure-to-pay systems, and states that your data is not used for training. A banner on the site says Icertis has acquired Dioptra.
